How ARG Niacin Supports Energy Metabolism and NAD Production

Niacin, as nicotinic acid, is a precursor to NAD and NADPH, coenzymes that drive hundreds of enzymatic reactions. These molecules are essential for converting food into usable energy, DNA repair, and cellular signalling. Each vegetarian capsule of ARG Niacin delivers 250 mg of vitamin B3 to help maintain optimal NAD levels, supporting the body’s natural energy production processes.*
